Catalytic semi‐hydrogenation through hydrogen transfer from carbohydrates as a sustainable hydrogen source over bimetallic PdCuFe₃O₄ nanoparticles

Abstract

We established a novel heterogeneous catalytic system for the semi‐hydrogenation of diphenylacetylene through hydrogen transfer from biomass as an abundant and cheap hydrogen source using a bimetallic PdCuFe3O4 nanoparticle catalyst. A wide range of carbohydrates from biomass sources were successfully utilized in the selective semi‐hydrogenation of diphenylacethylene in 2‐butanone/water.

Transition‐Metal‐Catalysed Transfer Hydrogenation Reactions with Glycerol and Carbohydrates as Hydrogen Donors

“…Recently, Bermejo and co-workers investigated the hydrothermal conversion of CO 2 (in the form of sodium bicarbonate and ammonium carbamate) [101] Recently, Kim and co-workers successfully developed a novel heterogeneous bimetallic PdCuÀ Fe 3 O 4 nanoparticle for the catalytic transfer semi-hydrogenation of diphenylacetylene using carbohydrates as an inexpensive and greener hydrogen donor. [102] Among the numerous possible combinations of catalysts, bases, hydrogen donors and temperatures were screened for the semi-hydrogenation of diphenylacetylene, the highest selectivity for cis-stilbene was observed with the bimetallic Pd 1 Cu 0.6 À Fe 3 O 4 as catalyst and glucose as a hydrogen source and K 2 CO 3 (1 equiv.) as a base in 2-butanone/water at 120 °C for 24 h (Scheme 46) .…”
